#35003 — What do you think of my CropImage class

I need to crop some images and decide to write a Java program for it.
At the moment it is very rudimentary, I plan to add some
functionalities and because I have very little experience with GUI
comments on how to implement the GUI better are welcome.


At the moment it is build with my camera's in mind and cropping for
InstaGram, but when it is seen as useful I will make it more generic.


I have a few problems, the most important are:
- After loading the first or a new image the first click makes the
  image disappear and painted again. Subsequent clicks do not have
  this problem.
- The original photo can be rotated. How can I find this out and make
  the cropped image also rotated?
- How can I add comment to an image?
- After saving the cropped image I want to display it also. What would
  be the best way to do this?

Some of the functionalities I want to add (other ideas are welcome):
- Working with different sets of cropping.
- Possibility to resize. (Select an area of 2.160x2.160 and crop it to
  1.080x1.080).
- Working with a database.

We'd need to see the code

That's in the image meta data (I have no clue how to find it)

You want to draw on the image or add meta data?

In another window maybe

Here's a crop component that I wrote years ago, I don't think I ever 
used it for anything but I can't remember.

import java.awt.*;
import java.awt.event.*;

import javax.swing.*;

public class CropComponent extends JPanel {
     BufferedImage bi,subImage;
     boolean mouseDown;
     int startX,startY;
     int endX,endY;
     int x,y,w,h;

     public CropComponent(BufferedImage bi) {
         this.bi = bi;
         setPreferredSize(new Dimension(bi.getWidth(),bi.getHeight()));
         addMouseListener(new MouseAdapter() {
             public void mousePressed(MouseEvent me) {
                 mouseDown = true;
                 startX = me.getX();
                 startY = me.getY();
             }
             public void mouseReleased(MouseEvent me) {
                 mouseDown = false;
                 subImage = CropComponent.this.bi.getSubimage(x,y,w+1,h+1);

That would help.  I was wondering if we were supposed to guess the code.
I ran it as is.  It is an odd interface.  I click Load and it prompts for a picture.  I select one and it displays it, with a barely noticeable black box in the corner.  I click around and it repaints it and the apparently non-resizeable box moves.  I wrote a class for displaying images and I recall having issues seeing it clear and repaint.  I'll have to lookup my workaround.  Then I click Crop and it opens a file open window.  I'm guessing this is supposed to save what's in the box to a new image file.  I type a file name that does not exist and it opens a new window.  The initial image window looks relatively small (640x480?) This new window looks huge, and the image is scaled to it? blurry, original looked sharp.
Given a day I could add some big improvements to this.  How much time have you spent on it?

I wrote a better explanation of what I wanted to accomplish as a reply
on my original post.

The non-re-sizeable is on purpose.

That would be nice,

Depends on the original input. The height and width are both divide by
eight because I want to see the complete picture.

No, the cropped image is unscaled. Your original picture is blurry,
but you did not see that because it was scaled down.

I know display the real size and the displayed size.

What is this "Swing" that you speak of?

The only graphical toolkit being developed by Oracle for Java is JavaFX.

Shouldn't be trying to crop JavaFX images?

I looked at your code and find it a bit disjointed (but I do have a 
rather linear outlook).  I guess it really depends on what you 
ultimately are trying to do though.  If I were going to write a GUI 
program to crop images today, I would:
	1) have a dialog to load an image (you have that) and display it along 
with its current dimensions
	2) have a method to scale the displayed image so that you can operate 
on images bigger than your monitor
	3) use something along the lines of my CropComponent to visually crop 
the image, showing the dimensions of the crop
	4) display the cropped image and its new dimensions, so it can be 
cropped again
	5) have a dialog to save the cropped image (you have that)

or get GIMP cause it does everything for free.  You might look at GIMP 
for their interface, it is really quite good.  The image is in its own 
dialog and all the tools are in a couple of others for handy access. 
Take a look at the Zoom options under the View menu to see what I mean 
about #2 above.

Of course we assume this is an exercise in learning Java?  If you just want an image editor the easy answer would be get a completed free application.  I use Paint.NET.

That was my point, if it is an exercise, Cecil should take a look at how 
a good image manipulation program works.

It is a little bit of both. I want to learn Swing and I want to crop a
piece of exactly 1080x1080 out of a picture. Something I cannot do
easily with an image editor.

Learning Swing would be the important part.  The cropping is pretty easy in Paint.NET.

At the moment I started I thought it was not easy, but it turned out I
knew not enough of Gimp. (Would not hurt to expand my knowledge of
that.) But I do not mind I started it. It never hurts to have a pet
project to learn things. :-D

Are you employed?  It could come in handy to learn code that has nothing to do with your job in case you would need it on the job someday, or for something else you say you know on an application for the next job.  Otherwise my pet project is my company's API, I've written most of it myself.  I even used a Timer in my image class so the user can select to rotate it 90 degrees and actually see it spin.

Self employed.

Nowadays most applications are written as a web application, so maybe
it will not help me to land a new project, but I find it interesting
anyway. :-)

That is a nice one.

Business applications usually have web GUI's.

But consumer applications are still often fat
(Windows desktop, Android, iOS etc.).

They are just rarely done using Swing.

:-)

Anyway - I think some basic Swing knowledge is part
of "basic knowledge" for Java developers. It may used
as a common reference context.

So I think you are doing the right thing.

These days it seems there's a lot of hybrids.  Last I checked for Java jobs they all wanted someone who knows the web, Java EE and similar technologies.
Many different methods to connect the data to the web, but the desktop application is still kicking.  Most likely the customer service people in house are not using a browser interface.

I don't do any web apps just Swing GUI applications and some specialized 
data presentation apps that use Swing components.  I'm sure I can't be 
the only one :-).

I am sure that you are not the only one.

If you look at Java job ads then something in the 1% magnitude
mention Swing skills.

If we say there are 10 million Java developers, then that
gives 100000 Swing developers.
